As shown in FIG. 4C , FIG. 5A and FIG. 5B , one end 1502 of the supporting link plate 150 and the second end 140 b of the flexible screen 140 are fixed to the frame 130 . As shown in FIG. 5A and FIG. 5B , the other end 1501 of the support link plate 150 is fixed to the first sub-housing 111 of the first housing 110 .

此外，請參考圖3，在本實施例中，第二殼體120包括支撐桿123，支撐桿123垂直於齒條R1。如圖5A與圖5B所示，支撐桿123位於可撓螢幕140與支撐鍊板150之間。第一顯示區141與第二顯示區142位於可撓螢幕140的外表面，支撐桿123抵接於可撓螢幕140的內表面。In addition, please refer to FIG. 3 , in this embodiment, the second housing 120 includes a support rod 123 , and the support rod 123 is perpendicular to the rack R1 . As shown in FIG. 5A and FIG. 5B , the support rod 123 is located between the flexible screen 140 and the support link plate 150 . The first display area 141 and the second display area 142 are located on the outer surface of the flexible screen 140 , and the support rod 123 abuts on the inner surface of the flexible screen 140 .

詳細來說，請參考圖3與圖6，第二殼體120還包括兩限位部125及兩軸承124，兩限位部125分別位於第二殼體120的兩側。軸承124可滑動地位於限位部125內。支撐桿123的兩端部分別配置於對應的軸承124。可撓式顯示裝置100包括兩彈性件160，分別配置於第二殼體120的兩限位部125內，且彈性件160抵壓軸承124，以使支撐桿123維持與可撓螢幕140的內表面之間的抵接關係。In detail, please refer to FIG. 3 and FIG. 6 , the second housing 120 further includes two limiting portions 125 and two bearings 124 , and the two limiting portions 125 are located on two sides of the second housing 120 respectively. The bearing 124 is slidably located in the limiting portion 125 . Both ends of the support rod 123 are respectively arranged on the corresponding bearings 124 . The flexible display device 100 includes two elastic members 160 , which are respectively disposed in the two limiting portions 125 of the second casing 120 , and the elastic members 160 press against the bearing 124 , so that the support rod 123 is maintained within the flexible screen 140 . Abutment relationship between surfaces.

這樣設計的好處在於，支撐桿123可以避免可撓螢幕140在第二殼體120的所述收合過程中因行程差而產生擠壓或皺折等不良狀態，其中行程差是指在收合過程中，由於齒輪G1與齒條R1、R2的間隙，所以在微觀上，可撓螢幕140的收合行程會落後第二殼體120的收合行程。一如前述，可撓螢幕140的可撓特性會因其不同狀態而產生形狀、尺寸的變化。為了讓裝置機構（例如第一殼體110與第二殼體120）的機構行程能與可撓螢幕140的變形量得以相符，本實施例藉由提供可相對移動的第一殼體110與第二殼體120，且藉由支撐桿123搭配軸承124、彈簧160用以支撐可撓螢幕140，以讓可撓螢幕140因張力而被拉緊而達到所需。The advantage of this design is that the support rod 123 can prevent the flexible screen 140 from being squeezed or wrinkled due to the stroke difference during the folding process of the second casing 120 . During the process, due to the gaps between the gear G1 and the racks R1 and R2 , microscopically, the retracting stroke of the flexible screen 140 will lag behind the retracting stroke of the second housing 120 . As mentioned above, the shape and size of the flexible screen 140 may vary in shape and size due to its different states. In order to make the mechanism stroke of the device mechanism (eg, the first casing 110 and the second casing 120 ) match the deformation of the flexible screen 140 , in this embodiment, the first casing 110 and the second casing 110 are relatively movable by providing the first casing 110 and the second casing 120 . The two casings 120 are used to support the flexible screen 140 through the support rod 123, the bearing 124, and the spring 160, so that the flexible screen 140 can be stretched by tension to meet the requirements.

圖7A與圖7B分別是本發明的一實施例的可攜式電子裝置於不同狀態的立體圖。在本實施例中，可攜式電子裝置10包括主機200以及所述可撓式顯示裝置100。可撓式顯示裝置100藉由樞接部T1以樞接於主機200且適於相對於主機200展開或閉合。當可撓式顯示裝置100相對於主機200展開時，第二殼體120適於相對於第一殼體110滑動而在所述抽出狀態與所述收合狀態之間轉換。7A and 7B are perspective views of the portable electronic device in different states according to an embodiment of the present invention, respectively. In this embodiment, the portable electronic device 10 includes a host 200 and the flexible display device 100 . The flexible display device 100 is pivotally connected to the host 200 through the pivot portion T1 and is suitable for unfolding or closing relative to the host 200 . When the flexible display device 100 is unfolded relative to the host 200 , the second casing 120 is adapted to slide relative to the first casing 110 to switch between the extracted state and the retracted state.

綜上所述，在本發明中，可撓式顯示裝置對應於可撓螢幕的可撓特性而設置能對應之第一殼體、第二殼體、框架，藉由第二殼體相對於第一殼體滑動而在抽出狀態與收合狀態之間轉換的過程中，第二顯示區收於第一殼體與第二殼體內，或是展開攤平第二顯示區，據以可以在抽出時以較大面積顯示，又可以根據需要收合以利於攜帶或減少其所占用的空間。To sum up, in the present invention, the flexible display device is provided with a corresponding first casing, a second casing, and a frame corresponding to the flexible characteristics of the flexible screen. When a casing slides to switch between the withdrawn state and the folded state, the second display area is retracted into the first casing and the second casing, or the second display area is unfolded and flattened, so that the second display area can be pulled out. When displayed in a larger area, it can be folded as needed to facilitate carrying or reduce the space occupied by it.

由於可撓螢幕能受到第二殼體的邊框由上而下的壓制及侷限，所以在第二殼體的抽出過程中，可撓螢幕只需朝單方向展開。在其他實施例中，可撓式顯示裝置可朝左右方向拉開而得到更大的顯示畫面。一如前述，可撓螢幕的可撓特性會因其不同狀態而產生形狀、尺寸的變化。為了讓裝置機構（例如第一殼體與第二殼體）的機構行程能與可撓螢幕的變形量得以相符，本發明藉由提供可相對移動的第一殼體與第二殼體並配合框架而達到所需。Since the flexible screen can be pressed and limited by the frame of the second casing from top to bottom, the flexible screen only needs to be unfolded in one direction during the extraction process of the second casing. In other embodiments, the flexible display device can be pulled apart in the left and right directions to obtain a larger display screen. As mentioned above, the flexible characteristics of the flexible screen will change in shape and size due to different states. In order to make the mechanism stroke of the device mechanism (such as the first casing and the second casing) match the deformation amount of the flexible screen, the present invention provides a relatively movable first casing and a second casing and cooperates with each other. framework to achieve the desired.
